We divide 86914395 by 129
We want to figure out the number of times 86914395 can be divided by 129.

Advancing to step 1:
129 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 129

Moving on to step 2:
129 can be fit into 86 0 times, resulting in a remainder of 86.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 86 after subtracting 0 from 86.
Take the next digit (9) from the dividend and append it to 86, then repeat: 869 / 129

On to step 3:
When dividing 869 by 129, we get 6 with a remainder of 95.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we subtract 774 from 869, we get 95.
Grab the next digit (1) from the dividend, add it to 95, then carry on: 951 / 129

Step 4:
129 can be fit into 951 7 times, resulting in a remainder of 48.
The next digit of our result is 7. 
Result so far: 67.0
Subtract 903 from 951 to get 48.
Fetch the next digit (4) from the dividend, attach it to 48 and continue: 484 / 129

Step 5:
The number 129 fits into 484 3 times, leaving a remainder of 97.
Put 3 as the next digit of the answer. 
Result so far: 673.0
Deduct 387 from 484 and we're left with 97.
Append the next digit (3) from the dividend to 97 and continue with: 973 / 129

Step 6:
The number 129 fits into 973 7 times, leaving a remainder of 70.
The number 7 becomes the next digit in our result. 
Result so far: 6737.0
If we subtract 903 from 973, we get 70.
Bring next digit (9) of the dividend behind the 70 and repeat the process: 709 / 129

Advancing to step 7:
129 goes into 709 5 times with a remainder of 64.
Put 5 as the next digit of the answer. 
Result so far: 67375.0
Deduct 645 from 709 and we're left with 64.
Take the next digit (5) from the dividend and append it to 64, then repeat: 645 / 129

Advancing to step 8:
129 can be fit into 645 5 times, resulting in a remainder of 0.
The next digit of our result is 5. 
Result so far: 673755.0
Deduct 645 from 645 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
When dividing 0 by 129, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 673755.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
If we divide 0 by 129, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 673755.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 673755.0 and a remainder of 0.0.
